Subject: [PATCH] MII bitbang driver should generate MII bus phy_mask
	dynamically

Current MII bitbang bus driver hard-codes the phy mask of mii_bus to
~0x09, which is actually specific to the FSL boards. This patch will
make the bitbang driver to generate MII bus phy_mask dynamically, by the
PHY irq info provided by the platform.
